Title: Digitally controlled nibbling machine tool - enables actual distance values and ratios to be corrected by conversion factor
Inventor: BROEMER GUENTER ING GRAD
IPC: G05B19/23
Filed: 1976-06-28
Abstract: Partial nominal values depending on programmed feed, an and partial actual values collected from a self-balancing travelled distance measuring system are added at specified time intervals to a full nominal distance and full actual distance. Speed nominal value for the feed drive controller is derived from the difference of these two distances, proportional to the pulling distance. When programming is in inches, while the metrical system is used, or vice-versa, partial actual values are passed through a calculating loop (17) with corresp. conversion factor. The ratio between the pulling distance and speed nominal value is corrected by the same conversion factor.

Filed: 1976-07-30
Abstract: Nickel-phosphorus layers are formed by electroless plating on activated non-conducting substrates, pref. to mfr. passive components, esp. resistors with a low temp. coefft. of resistance (TCR). An aq. plating bath is used contg. Ni ions, hypophosphite ions and (a) a hydroxy-polycarboxylic acid, or an amino acid forming a Ni complex soluble in an alkaline pH. A pH of 8-14 is maintained during plating, and the coating obtd. is heat treated.

A specified surface resistivity is pref. obtd. by adjusting the plating time. The coating is pref. heated 2 h at 80-100 degrees C. A homogeneous, fine grained layer can be obtd. with a phosphorus content high enough to obtain a TCR 20 ppm/degrees C. The plating bath is stable, so a close tolerance can be achieved on the desired surface resistivity, the latter being obtd. by the immersion time.

Title: Device for removal of wearing surface of a tyre - allows easier maintenance and has less tendency to overheat (SF 31.12.76)
Inventor: IMMONEN KAUKO ILMARI
IPC: B23D71/02
Filed: 1976-11-10
Abstract: A machine which removes the wearing surface of a tyre before resurfacing includes a number of ring shaped cutting bits held between two disks which are fixed together. The disks rotate at right angles to the tyre and a speed ten times that of the tyre. Material is removed from the tyre by a slicing action and discharged through the open centres of the rings which also provide air cooling.

Title: Bearing for swing bridge - has rubber or plastic sliding surfaces lubricated by grease supplied at high pressure
Inventor: LEONHARDT FRITZ PROF DR ING
IPC: E01D19/04
Filed: 1977-04-27
Abstract: The pivot bearing of a swing bridge has a bearing surface (4) of rubber or plastic such as PTFE sliding against a metal surface (10). In conventional bearings of this type the initial charge of lubricating grease leaks away from the the joint surface resulting in an increase in friction.
